UPDATE: Official statement, Tom Petty, dead at 66.

After suffering cardiac arrest Sunday night, Tom Petty was confirmed dead by CBS News earlier today (which BrooklynVegan also reported via CBS News), though now it's unclear if that is actually the case. CBS cited the LAPD as confirmation who have since stated they have no information:

TMZ, meanwhile, who reported that Petty had been pulled off life support earlier in the day, reported as of 1:35 PM Pacific, that he was still "clinging to life," though their sources said that a chaplain had been called to his hospital room and that he was not expected to live through the day. There has still been no official statement from anyone.

Petty had just wrapped up his 40th anniversary tour with The Heartbreakers.
